Cryptocurrency price comparison

I would like to build a software in two parts. The first part will collect BUY/SELL rates via API from crypto-currency exchange web-sites globally and plot them on a BUY and a SELL graph.

The second part of the software will detect arbitrage opportunities and create alerts of potential opportunities. For the moment, this project is limited to the graphing part ONLY. However, once you deliver the graphing system you will be required to continue development into the second part.

I would like to build a database of information which we store for upto 12 months at a time. As such, the storage requirements for data will be large and you will need to consider this.
